KB Pup

This is the earliest model
of the Kolster-Brandes Pups. This one was introduced in 1930
whilst a similar looking model, with a slightly different cabinet,
and just a little styling, was introduced a year later.

This model is decidely utilitarian
in looks, has only two valves and uses a large moving-iron loudspeaker
with a paper cone, adjustable for volume by the brass knob in
the centre.

Basic in the extreme...The utiliarian
look also applied to the interior.

Tuning and reaction controls
are at the top and are fitted with simple 0-180 dials made from
thin black bakelite.

panel

Clearly the set was designed to
be as cheap as possible. It's surprising it was fitted with a
back panel. This slides upwards to reveal the space for the batteries
and a label proclaiming that the set will only work with British
Valves. Maybe this was a get-out when complaints were made about
poor reception?

For £4:10:0d what did one expect
in 1930? If you look elsewhere on this site you'll see a Lotus
radio made around the same period. That cost nearly four times
the Pup; although when you add the cost of a grid bias battery,
an HT battery and a 2-volt accumulator to the cost of the Pup...
and added costs of regular replacements and the cost of charging
the accumulator, maybe the mains Lotus was a good bet? The components
are probably mounted on the back of the chassis.. I hope so!
